IN THE MATTER 


OF THE 


Petition of George H. Corliss, 

FOR AN EXTENSION OF HIS 


LETTERS PATENT, 

FOR IMPROVEMENTS IN 

4 



PROVIDENCE : 

PROVIDENCE PRESS COMPANY, PRINTERS. 



* 








Petition for Extension of Patents. 


To the Hon. the Senate and House of Representatives in 
Congress Assembled: 

The petition of Geo. H. Corliss, of the city of Prov¬ 
idence, State of Bhode Island, respectfully represents : 

That your petitioner is the inventor of certain im¬ 
provements in Steam Engines, for which he received 
Letters Patent of the United States, dated March 10th, 
1849: 

That subsequently these Letters Patent were surren¬ 
dered, and on the 12th of July, 1859, were reissued to 
your petitioner in six separate parts, for six distinct 
improvements embodied in the original patent: 

That upon the expiration of the term of 14 years,— 
on the 10th March, 1863, upon due proceedings accord¬ 
ing to law, an extension of these Patents was granted 
by the Commissioner of Patents for the term of 7 years, 
which term will expire on the 10th March next: 

That after the granting of said extension, the time 
and pecuniary resources of your petitioner were largely 
and for a long time diverted from the development of 
his own inventions to the execution of certain contracts 
for machinery for the United States Navy, in which 
those inventions were excluded: 

That said improvements are of great and permanent 
value to the industrial interests of the country: 

That your petitioner has not been adequately remu¬ 
nerated for his inventions, and that the failure to secure 



4 


such remuneration has not arisen from a want of rea 
sonable diligence and persistency in bringing them into 
use: 

That said improvements, being connected with the 
development of power in the steam engine, are of such 
a nature that it has required much time, and a large 
outlay of money to establish their merits: 

That as soon as the merits of said improvements were 
beginning to be acknowledged, so that they possessed 
some mercantile value, your petitioner found himself 
involved in a course of litigation, which has made the 
history of his patents for nearly twenty years a record 
of lawsuits, and although the courts of the United States 
have vindicated his course in respect to all of this 
litigation, and have established the validity of his 
Letters Patent, yet the process of vindication has been 
so expensive as to absorb a large proportion of the 
profits of the invention, and so prolonged, that the Ex¬ 
tension now sought for is necessary to render his success 
in said litigation of any practical value : 

That all the rights of property in these inventions 

i 

covered by said Letters Patent, heretofore enjoyed by 
your petitioner have not been equivalent to an exclusive 
use of the same for a term of seven years: 

Your petitioner therefore asks for an Extension of 
his said patents for another term of seven years, in 
order that he may secure to himself an equivalent of 
the original term of 14 years, for which his Letters 
Patent were originally granted. 

All of which is respectfully submitted for the consid¬ 
eration of your Honorable body. 

(Signed) GEO. H. CORLISS. 

Washington , D. C.. Dec. 9, 1869.

The following parties, users of my improvements, and 
representing the most important industrial interests of 
this country, join in asking the favorable consideration 
of my petition, upon the following invitation: 

Providence, R. I., 1870. 

To 

If the object of the enclosed Petition meets with your approval, 
please sign and return same to me, and oblige, 

Yours, very respectfully, 

GEORGE H. CORLISS. 

To the Honorable Senate and House of Representatives , of the United 
States , in Congress assembled : 

The undersigned, having been informed of the pendency of the 
petition of George H. Corliss, of Providence, R. I., for an Exten¬ 
sion of his Letters Patent, for “ Improvements in Steam Engines,” 
and knowing by the USE of said Improvements that they are of 
great practical value to the industrial interests of the country, and 
believing that he has not been adequately remunerated therefor, do 
join in an earnest request that his application may receive the favor¬ 
able consideration of your Honorable body.

After an experience of about twenty-two years in the 
introduction of these improvements into manufactories 
in all branches of industry, where the best engines of 
previous construction had been used, I know of no in¬ 
stance where the result in saving of fuel has been less 
than thirty per cent.; and this saving has been accompa¬ 
nied by an improved regularity in the speed, giving from 
live to twenty per cent, increase in production. 

The value of this invention to the present users of 
the Engines containing the same in this country, is not 
less than Two Millions o f Dollars per annum. 

In 1855 I visited the steam cotton mills of Newbury- 
port and Portsmouth, where about 90,000 spindles were 
in operation, and made proposals to them to replace the 
engines they were then using, by those embodying my 
improvements. The engines which I found in these 
mills were the best known in this country before the 
introduction of my invention. During this and the fol¬ 
lowing year, my engines were erected in all these mills. 
In two of them the price to be paid by the purchasers 
was to depend upon the amount of fuel saved, and this 
saving was to be determined by an accurate test in the 
comparative consumption of coal for one year; the 
weighing of the coal being in charge of the purchasers, 
was a guarantee that the saving was not overstated, and 
yet the result of these changes was, in each instance, a 
saving of over thirty-three per cent, in the consumption 
of fuel; and the average increase of manufactured goods, 
arising from the improved regulation, was not less than 
seven per cent. Upon the basis of the results secured 
in the steam cotton mills of Newburyport and Ports¬ 
mouth, it is proved that the introduction of my improve¬ 
ments in a single cotton mill of 40,000 spindles y requiring 


14 


450 horse power, effects an annual saying in fuel, amount¬ 
ing to more than my annual receipts have been from this 
invention ; and the cotton machinery now operated in this 
country by engines embodying my improvements, is 
more than equal to seventy mills of 40,000 spindles each . 

In 1852 I furnished Messrs. Crocker Brothers & Co., 
of Taunton, Mass., an engine embodying my improve¬ 
ments, to replace one they then had in use, upon the 
conditions that the new engine was to do the same work 
with two tons of coal per day, which had required five 
tons per day; and failing to accomplish this saving in 
fuel, a forfeiture was to be made of one dollar per 
pound for every pound consumed per day above that 
reduced amount. The new engine was also to regulate 
its own motion under all the excessive changes in power 
which occur in a Rolling Mill, and thus save the employ¬ 
ment of a man at the regulating valve ; and although the 
work of the mill was increased about one-third by the 
addition of new machinery, and the power varied from 
60 to 360 horse power in a minute, all these results 
were accomplished. A full account of this transaction 
is set forth in detail in the affidavit of Samuel L. Crocker, 
printed herewith. 

A careful examination into the results of this case 
reveals the fact, that this one engine, now in its eighteenth 
year of service, has been a source of more profit per annum 
to its owners, than these improvements have yielded me per 
annum, as the inventor, in all the engines in which they 
are embodied in this country. 

Among the users of my improvements who have joined 
in asking the favorable consideration of my petition, is 
the Wamsutta Mills Co., of New Bedford, Mass.; and I 
herewith submit an affidavit of the agent of the corpo- 


15 




ration, setting forth the extent to which my improve 
ments have been adopted in their mills, and the impor¬ 
tance of the same to their success in the use of steam 
power in the manufacture of cotton goods. They com¬ 
menced the use of my improvements in 1848, and as 
they have added to their mills from time to time, they 
have purchased my engines, and no others. Their expe¬ 
rience, therefore, furnishes no means of a comparison 
of my engine with others; but having as data for esti¬ 
mate, the facts furnished by the agent in regard to the 
amount of power used, and the length of time such use 
has been continued, and applying the basis of saving 
realized at the Newbury port and Portsmouth mills, it is 
proved that this one Corporation have already profited 
more by the use of my improvements , than I have ever 
received from my patents ; their profit being at the present 

time , $ 228 , 480 . 00 . 

The Washington Manuf’g Co., of Gloucester, N. J., 
furnishes another illustration of the value of my inven¬ 
tion to the industrial interests of the country. After 
using other engines for several years, (one of which 
was a “Sickles engine,”) they adopted my improvements, 
and now report, (as per statement of their President 
and Superintendent, printed herewith,) that they have 
actually saved by this change, during the last fourteen 
years and four months, in the item of Coal alone, 

$1 oo 9 705.©o. 

As to the difficulties and delays encountered in intro¬ 
ducing my improvements, I have to say that I com¬ 
menced the development of my improvements in steam 
engines in 1846, and completed an engine embodying 
the same in 1848, and although this first engine effected 
a saving of two tons of coal per day, and demonstrated 


its power of self-regulation under great changes of 
resistance, and gave the most perfect satisfaction to the 
users; yet the invention encountered so much opposition 
and prejudice, that few parties could be induced to 
adopt it. The most promising field of effort open to me 
was among those who were using steam engines, and 
knew the cost of running them. But even here, my 
proposals sometimes remained under consideration five 
years before they were accepted, and this occurred while 
the engines I had put in operation were constantly 
demonstrating that their entire cost could be saved to 
the users in from two to four years; and in scores of 
instances, negotiations were pending for two and three 
years, before I could succeed in introducing my improve¬ 
ments. The reluctance manifested by manufacturers in 
incurring the cost of a new engine, as also the fact, that 
a change in engines generally involved an entire suspen¬ 
sion of the work in the manufactory, during the removal 
of the old, and the erection of the new, together with 
the absence of a sufficient confidence in the result to be 
derived from a change in their particular case, prolonged 
these delays in introduction. My efforts generally at 
first, only stimulated an attempt on the part ot the own¬ 
ers and builders of engines of the old construction, by 
repairing and readjusting the same, and in some instan¬ 
ces changing the boilers, to accomplish the results that 
I proposed to secure by my improvements. 

An illustration of this occurred in Philadelphia in 
connection with a flouring mill manufacturing three 
hundred and fifty barrels per day, where some two years 
were occupied in this way, and after the parties had 
accomplished all they could, by repairs, readjustment 
and the adoption of a new set of boilers, I furnished 


17 


them with a new engine, embodying my improvements, 
at the regular market price; stipulating, under a forfeit¬ 
ure, to manufacture with this engine, using the same 
machinery and boilers which had been previously em¬ 
ployed, one hundred and forty-five barrels of fiour with 
the same amount of fuel which had been previously 
required for the manufacture of one hundred barrels. 
Within thirty days after the starting of the new engine, 
the parties reported one hundred and forty-seven and a 
half barrels as the actual result, with the same amount 
of coal which had been previously required for the 
manufacture of one hundred barrels, and paid the full 
price for the engine. 

In the case of the Washington Manufacturing Co., 
alluded to, where an average annual saving of $13,305, 
for the last fourteen years and four months, has been 
realized by the use of my improvements, I labored for 
about three years in inducing them to adopt the same, 
and at last succeeded only by guaranteeing to do the 
same work with four tons of coal per day, that had 
required eight or nine tons, and agreeing to pay $5,000 
per ton forfeiture, for every ton consumed per day over 
that reduced amount. 

The case of Crocker Bros. & Co., to which I have 
already referred, is another illustration of the kind of 
contracts which I was obliged to enter into to secure 
the adoption of my invention. In this case, what I 
promised was equivalent to the gift of the entire engine 
of two hundred and fifty horse power for less than two 
years’ saving in fuel alone ; and what was actually real¬ 
ized in increased work and improved regulation, was 
equivalent to the entire cost of the engine in about fif¬ 
teen months’ service. And to such straits was I then 


2 



18 


driven, that I was glad to have even such terms accepted. 
And this occurred more than four years after my improve¬ 
ments had been put in operation. 

But the greatest obstacle encountered in the introduc¬ 
tion of my improvements, arose from litigation. The 
first suit was brought against Corliss, Nightingale & Co., 
in 1850, upon a patent granted to F. E. Sickles in 1845. 
This suit having failed, another was instituted against 
the same parties, on another patent of Sickles’, dated 
May 20th, 1842 ; and upon this last patent, about ninety 
suits were pending at one time against the users of my 
engines in different parts of the country. After many 
trials, in different forms, before the Courts of different 
Districts, all these suits failed. The owners of the said 
patent of 1842, being also owners of other patents of 
Sickles’, dated in 1844 and 1845, the litigation was con¬ 
tinued, under several reissues of the last named patents, 
until 1863, when the opinion of Mr. Justice Clifford, in 
my favor , practically closed the contest. Although the 
case was afterwards taken to the Supreme Court, it was 
finally dismissed without argument. 

The exclusive ownership of these Sickles patents for 
land engines from April 30th, 1850, to the 16th October, 
1852, was held by Charles T. James, who began this 
litigation. After that date, (1852,) all the Sickles patents 
for land engines, were held by Robert L. Thurston, 
Henry W. Gardner and Gideon G. Hicks; and these 
parties, including the said James, were at one time in 
business as manufactures of engines under the Sickles 
patents. Afterwards, the said Gardner and his asso¬ 
ciates, having failed in several attempts to apply the 
Regulator to the Sickles Cut-off, abandoned the manu¬ 
facture of engines under the Sickles patent altogether; 


19 


and adopted the manufacture of a different form of 
engine, claimed as the invention of Noble T. Greene, 
(who was at one time associated with said Gardner as 
“ Thurston, Greene & Co.”) Being satisfied that these 
engines were infringements of my patents, I instituted 
suits against the users of the same in Rhode Island, and 
after four jury trials, without reaching any result, I 
reissued my Letters Patent in 1859 and filed a Bill in 
Equity in the District of Connecticut, against the 
Wheeler & Wilson Manufacturing Company, which was 
regarded as a test case under my patents. After a full 
hearing before Mr. Justice Nelson and Judge Shipman, 
it was decided that this Greene engine, as manufactured 
by these parties, infringed four of my Letters Patent. 

The Courts of other Districts have followed this decis¬ 
ion, and issued injunctions against the particular form 
of infringement which was involved in that suit. 

The details of my statement of expenditures, estab¬ 
lish the fact that I have used reasonable diligence in 
endeavoring to secure to myself the exclusive use of my 
inventions, which the law is intended to give. I have 
instituted proceedings, which are still pending, against 
other parties using engines, containing, as I believe, 
under different forms of mechanism, infringements of 
my rights under these patents. But had I under¬ 
taken all the suits necessary to secure such exclusive 
use, against the different forms of infringement which 
appeared from time to time, the expenses of such a 
course would have absorbed every dollar that I have 
received for my invention. 

In presenting the foregoing statement of my account 
with my Letters Patent, I am able to draw an equitable 
line between my interest as a manufacturer of steam 


20 


engines, and my interest as the inventor of these improve¬ 
ments, by my account of royalties, extending over the 
whole period of the existence of my patents. I have 
never received from my associates in the manufacture of 
steam engines, any consideration for the use which they 
have made of my improvements in Steam Engines, other 
than that expressed in said account. My receipts for 
royalties include payments from eleven builders of 
engines, seven of whom, having manufactories in Rhode 
Island, Pennsylvania, Massachusetts, Delaware, New 
York and California, have been at liberty to build as 
many engines as they pleased, of any size they pleased, 
to be located wherever they pleased, and to get any 
price for the same they could; affidavits of three of 
whom are printed herewith. Thus, the public have had 
the full benefit of an unrestricted competition between all these 
licensees . 

The small amount of royalties received from all other 
licensees, except my associates, indicate the small 
amount of business they were able to command. The 
highest royalties paid by any of these builders, prior to 
March 10th, 1866, was $1.50 per square inch of area 
upon the piston for all cylinders under 24 inches diame¬ 
ter, and for 24 inches diameter and upwards, $1.12J. 
Prior to March 10th, 1863, the several firms, with which 
I have been associated in the building of steam engines, 
have paid for royalties on the engines manufactured by 
them containing my improvements, including the sums 
paid prior to that date in the defense of the claims set 
up by Sickles, a rate greater than that paid by other 
builders. Since March 10th, 1863, the royalties paid 
by the Corliss Steam Engine Co. have been, on engines 
less than 24 inches diameter of cylinder, $1.50; and on 


21 


larger engines, $1.12 J per square inch of area; thus, 
placing them at that date on the same footing with other 
builders. And these rates were established by a vote of 
the company March 20, 1863, when my interest was 
iolro of the stock of the company, and are still in force. 
The builders whose affidavits are printed herewith, agree 
in the statement that the profits derived from the manu¬ 
facture of these engines, after paying the royalties, has 
not been greater than the profits derived from the gen¬ 
eral business of their several shops; and the result of 
an attempt on my part in 1866, to increase my income 
from royalties by raising the rate, is set forth in the affi¬ 
davit of H. S. Fairbanks, herewith. 

The vast disproportion of my receipts for royalties, 
between the several firms with which I have been con¬ 
nected, and all the other licensees together, is evidence 
of reasonable diligence on my part in the effort to intro¬ 
duce my invention, and of the fact that the balance of 
my account with my Letters Patent, has been materially 
increased by my position as a manufacturer of steam 
engines. 

All my licensees were exempt from the responsibility, 
care and labor of the defensive litigation growing out 
of the claims of Sickles, except my associates; who, in 
consideration of the payment of a half license fee, 
assumed certain expenses as per statement herewith, 
while I assumed the personal labor of conducting this 
litigation, without which, my Letters Patent were ren¬ 
dered worthless. This labor consisted in preparing 
models, investigation of the history of the art as relating 
to the steam engine, assisting counsel in the mechanics 
and preparation of the case, procuring testimony and 
witnesses, personal attendance in court in the several 


22 


trials, which often monopolized my time for whole 
months together. And the same kind of labor and 
effort was required in all that portion of the litigation 
to which I was driven by infringers in the establishment 
of my rights ; and this labor has extended over a period 
of twenty-one years, with but little interruption, which 
occurred during the existence of the civil war. In 
addition to all this diversion from my regular business, 
I was necessarily involved in a continual succession of 
assumptions of the most hazardous contracts, which 
were in no sense a part of my legitimate business, as a 
manufacturer, but were undertaken because of my inter¬ 
est in these Letters Patent, and to establish their value, 
in order that I might secure some proper remuneration 
for the same. The development of the invention, in its 
various applications, has required a large amount of 
planning and drawing, which in many cases was equal 
to a large amount of the royalties resulting therefrom. 
For all this personal service, I have charged in my 
account the sum of $2,500 per annum. I know that 
this is much below what I should have had to pay for 
the same service, if performed by others; and the dam¬ 
age which has resulted to me as a manufacturer, in with¬ 
drawing my personal attention from the general business, 
has been at least treble the amount I have charged there¬ 
for. I deem this item of my account indispensable to 
a proper exhibit of the actual profits derived from my 
Letters Patent.

[D.] 

Taunton, Sept. 22, 1857. 

Corliss Steam Engine Co.: 

Gentlemen, —In compliance with your request, we 
will make a statement in relation to the substitution of 
one of your improved engines, in our rolling mill, in 
July, 1852, in place of one of the old construction, put 
in by us, in the winter of 1846-7. 

In March, 1852, you proposed to build and set up in 
our mill, within ninety days from the date of the con¬ 
tract, an engine which you guaranteed should be capa¬ 
ble of driving one-third more work thau we were doing. 
The average amount of coal then used by our engine, 
was about five (5) tons Pennsylvania chestnut per day. 
You guaranteed that your engine would do the same 
work with two (2) tons, or you would forfeit one dollar 
per pound for every pound used above that amount. 

The new engine was to regulate its own motion, under 
all the excessive changes in power which occur in our 
rolling-mill, (this could not be accomplished with the 
old engine, although we employed a man constantly at 
the regulating valve), and be fully adapted to all the 
peculiar requirements of a rolling-mill, or you would 
remove it from our mill wholly at your own expense, 
after a trial by us of sixty days. 

Your proposals were accepted; the engine was put 
in successful operation within the time specified, and 
came up fully to all that was proposed to be accom¬ 
plished. 

In your proposition, there were no specifications as to 
the size of the new engine; that matter being left 
wholly to your discretion. We were quite surprised, at 
the time, to find that you were putting in a 32-inch 






26 


cylinder by 6 feet stroke, under the guarantee to do a 
third more work than we were able to do with the old 
engine, which had a cylinder 38 inches diameter by 7 
feet stroke. The result has shown that your improve¬ 
ments in the application of steam, have enabled you, 
with the smaller cylinder, to give the increased power 
required. 

Although we have increased our work about one-third 
by the addition of machinery, and have also increased 
the production of our mill, by the uniformity of motion, 
secured by your improvements in the mode of regula¬ 
tion; yet our average consumption of Pennsylvania coal, 
when we have used it, has not exceeded two gross tons 
per day. Finding that our engine ran with so small an 
amount of steam, compared with the old engine, we 
tried the Rhode Island coal, which we have used from 
that day to the present, with entire success, at the aver¬ 
age amount of 5,000 pounds per diem. 

Our power frequently varies from 60 to 360 horse 
power within a minute, without perceptibly affecting the 
speed of the engine. 

Your engine is now driving our mill as satisfactorily 
as ever, and we should perhaps add, that we use the 
same boilers which supplied steam for the former engine, 
without change in their setting or management, except¬ 
ing that with the old engine we had to force our fires 
with a blower, which we have not used in making steam 
for the new engine. 

Yours, truly, 

CROCKER BROS. & CO.

Engines.

That we have in operation in said mills, three Corliss 
engines, the first of which we put in operation in our 
No. 1 mill, in 1848, and has since been working with 
an average of two hundred horse power. In the year 
1853 we built our No. 2 mill and purchased the second 
engine from Mr. Corliss, which was put in operation the 
7th of January, 1854, and has since been running with 
an average of three hundred and seventy-five horse 
power. In 1861 we built our No. 3 mill, and purchased 
the third engine of Mr. Corliss, which has been in opera¬ 
tion therein since January 8th, 1862, with an average of 
three hundred and seventy-five horse power; and our 
company have now built their 4th mill, and have ordered 
from Mr. Corliss a fourth engine, which is nearly com¬ 
pleted, for which seven hundred horse power will be 
required. 

These engines, embodying the improvements of Mr. 
Corliss, combine the highest degree of economy of fuel 
with the most perfect regulation of speed ; and the use 
of these engines has contributed largely to the success 
of the Wamsutta Mills Co. in the manufacture of cotton 
goods by the use of steam power.

Newburyport, Aug. 25th, 1857. \ 

Corliss Steam Engine Co. : 

Gentlemen, —In reply to your request for a state¬ 
ment in relation to the change of engines in our mills, 
I would say, that about two years since we were induced 
to make the change by your proposal to furnish us new 
engines for the saving of coal in five (5) years, we hav¬ 
ing previously stated to you our annual consumption of 
fuel. Afterwards, at our solicitation, you gave us the 
market price for the work, allowing us to make a choice 
between that price and the saving of coal, which 
decision was to be made before the new engines were 
operated. 

We hesitated for some time, as to which way the pay¬ 
ment should be made, for we learned upon inquiry, that 
no mills in the country were doing so well as ours, 
except those that were driven by engines embracing Mr. 
Corliss’ improvements. We, however, decided to pay 
your market price for the work, and the result of about 


30 


two years’ running shows, that we have saved a hand¬ 
some sum of money by settling in that way. 

Our two mills contain 17,360 cotton spindles, requir¬ 
ing about 200 horse power, and we use the same boilers 
which were put in when the mills were built. Our 
arrangements for heating remain the same, and we con¬ 
tinue the same arangement of gearing; consequently 
we have the best opportunity of testing the merits of 
your engines, as the change was made solely in the en¬ 
gines. 

We have gained a great advantage from a more per¬ 
fect regulation of speed. 

I w 7 ould simply add, without going into the details of 
the consumption of fuel, that we are obtaining fifty (50) 
per cent, more work from each pound of coal consumed 
than we did with our former engines. 

Respectfully yours, 

John Balch, 

Treasurer Bartlet Steam Mills.

respects gives us the same satisfaction we then ex¬ 
pressed. In 1867 we made an addition to the mill,

derived from another “ Corliss Engine,” of the same 
dimensions and construction as that referred to in the

Office of the Ocean Steam Mills 
Newburyport, Aug. 17, 1859. 


Corliss Steam Engine Co. : 

Gentlemen, —I comply with your request, and below 
give a statement of the facts you call for. 

Our mill contains 9,408 spindles, “ Mason’s Self-Act¬ 
ing Mules,” 208 looms, and we make No. 35 yarn—30 
in. print cloths. 

Our former engines were considered first-class ma¬ 
chines, and were perfectly satisfactory to us until we 
received your proposals. The proposals were under 
consideration with us long enough to waste coal to the 
amount of one-half the cost of the change of engines, 
before our company could be induced to abandon the 
former engines. You proposed to take the engines as 


32 


they stood, and furnish the new one for the saving of 
fuel for 2 1-2 years running, or the sum of $3,000 
cash. 

No change was made in the boilers, neither was any 
alteration made in the heating apparatus, or anything 
connected with the use of steam, excepting the engine 
proper. 

We decided to give you the $3,000, which has 
proved a good operation for our company, as the sav¬ 
ing of fuel will amount to about $3,000 in two (2) 
years. 

In addition to the saving of fuel, we have experi¬ 
enced a great advantage resulting from a more perfect 
regulation of the speed of the engine, which has given 
us a larger production of cloth. 

Our average consumption of coal with the former 
engines was 6,000 lbs. per day; this was for the engine, 
heating the mill, and all other purposes for which we 
require steam. The average amount used by the new 
engine, for the same purposes, is 4,200 lbs. per day. 

Yours, &c., 

E. S. LESLEY, 

Agent Ocean Steam Mills. 


In the Matter of the Petition of George H. Corliss , for

I, Henry S. Fairbanks, of Central Falls, in the county 
of Providence and State of Rhode Island, on oath depose 
and say, that I am Agent and Treasurer of the Foundry 
and Machine Co., of Taunton, Mass., and have been 



33 


since 185G. In that year (1856,) the said company 
commenced the manufacture of steam engines embody¬ 
ing the improvements patented by Mr. George IT. Cor¬ 
liss, undei an arrangement for the payment of certain 
royalties ; during which time the, said company have 
manufactured and sold fifty-seven engines, embodying 
said improvements, and have paid the said Corliss as 
royalty on the same, the sum of twenty-two thousand 
seven hundred and three and dollars, $(22,703.05); 
one thousand eight hundred and eighty-seven and ^ 
dollars of which was paid prior to the 10th day of 
March, 1863, and there is now due the said Corliss on 
this account, the sum of two thousand and thirty-one 
and joo dollars, ($2,031.02.) That during the whole 
period from 1866 to the present, said company has been 
under no restrictions from the said Corliss, as to the 
sizes of the engines, localities where they were to be 
used, or price to be received therefor. The profits we 
have received tor these engines after paying the royal¬ 
ties, have not been greater than'that derived from other 
branches of our business. Some parties with whom we 
were negotiating for the sale of some of these engines 
in 1866, refused to pay the increased price required, to 
cover the increased royalty then demanded by Mr. Cor¬ 
liss, and the order for the work was lost on this account; 
and recently, we lost an order for an engine of one hun¬ 
dred horse power, because we would not make a con¬ 
cession of fifty dollars from a price, which was as low 
as we could afford to make it after paying the royalty. 

The said company have no arrangement or understand¬ 
ing covering the future use of said improvements. In 

the course of our business we have had occasion to sub- 

* 

stitute the “ Corliss engine,” for engines of ordinary

construction regulated by a throttle valve, and in no case 
has the saving of fuel resulting from said substitution 
been less than thirty per cent., and a better regulation of 
the speed of the engine attained.

Steam Engines. 

I, Lewis Miller, of Chester, in the State of Pennsyl¬ 
vania, on oath depose and say, that I am a member of 
the firm of Miller & Allen, of said Chester, which firm 
has been engaged since the spring of 1859, in manufac¬ 
turing steam engines embodying the improvements of 
the said George II. Corliss, during which time we have 
built one hundred and three Corliss engines, on which 
we have paid the said Corliss for royalties, the sum of 
five thousand six hundred and eighty-four dollars and 
ten cents, ($5,684.10); and there is now due to him the 
sum of nineteen thousand four hundred and eighty-eight 
dollars and fifty cents, ($19,488.50,) on this account. 
The saving of fuel by the use of these Corliss engines 
over the best engine which has been by us replaced by 
them, was not less than thirty-three per cent., and over 



35 




many of the engines replaced by the Corliss engine, the 
saving was much greater. There are now running in 
our town, thirty-one Corliss engines, out of some thirty- 
seven in all. The introduction of these engines, in 
almost every instance, has required a great amount of 
personal solicitation on our part, and in many cases, a 
guarantee of a large saving in fuel. The business of 
our firm is the building of boilers, shafting, gearing, 
saw mill and rolling mill machinery, and steam engines. 
The latter branch constitutes about one-third of our 
manufacture, and the profits on the same, after paying 
our royalties, have been less than that received upon 
the other branches of our business. 

Since 1859 we have been under no restrictions from 
the said Corliss as to the sizes of the engines, localities 
where they were to be used, or price to be received 
therefor, and we have no arrangement covering the 
future use of said improvements.

Hon. George H. Corliss , Providence , R. L: 

Dear Sir, —In response to your request for a brief 
statement of the results realized by us through the intro¬ 
duction of your improved engines in our mills at Glou¬ 
cester, N. J., we have the pleasure of stating the follow* 



36 


ing facts. We have two mills requiring about 360 and 
250 horse power, respectively. In 1854, you made us 
a proposal to furnish one of your engines for our No. 2 
mill, guaranteeing, under a heavy forfeiture, to furnish 
the power of this mill with less than half the amount 
of coal then required. The terms of your guaranty 
were more than fulfilled by the operation of your engine; 
this result induced us to order of you new engines for 
our No. 1 mill, which were put in during the succeeding 
year, and the result of this change was equally satisfac¬ 
tory. By reference to our accounts, we find that we have 
realized by the use of your engines during the time they 
have been in operation, an actual saving compared with 
the engines formerly used, of no less than thirteen thou¬ 
sand three hundred and five dollars ($13,305.00) per 
annum, netting for the fourteen years and four months, 
(14 years and 4 months) — average time since starting 
of the engines — an aggregate of one hundred and ninety 
thousand seven hundred and five dollars, ($190,705.00,) 
in the single item of coal. To this we add other advan¬ 
tages, such as uniformity of speed and increased relia¬ 
bility in the operation of our mills, which your engines 
have enabled us to experience. 

In justice to yourself we would further state, that our 
former engines were made by first class builders, and 
were always considered to be as good as any in the mar¬ 
ket. In making our estimates of savings, we have not 
based our calculations upon any experimental trials, but 
upon the actual products of our mills and the actual 
weights of coal consumed for whole years taken togeth¬ 
er, both with the original engines and with the “Corliss” 
engines ; coal being estimated at five dollars ($5.00) per 
ton. Yours truly,

I, William A. Harris, of Providence, in the County 
of Providence, and State of Rhode Island, on oath de¬ 
pose and say, that I am engaged in the manufacture of 
steam engines embodying the improvements patented by 
George H. Corliss, and have been so engaged since 
August, 1864, during which period I have manufac¬ 
tured fifty-seven engines with said improvements, and 
have paid the said Corliss on account of the Royalties, 
the sum of six thousand dollars, and there is still due 
the said Corliss on said account, a balance of eighty- 
four hundred and sixty-two dollars and twenty-four cents; 
and during the said time I have been under no restric- 



38 


tion whatever from the said Corliss, as to the sizes ot 
the engines, localities where they were to be used, or 
price to be received therefor. That I have no arrange¬ 
ment or understanding with the said Corliss, covering 
the future use of said improvements. In the month of 
March, 1868, I contracted with the Meriden Britannia 
Co., to furnish them a 44 Corliss engine.” This engine 
was afterwards tried in competition with another engine 
of the same size, each having a cylinder twenty inches 
in diameter, and a stroke of four feet. A printed con¬ 
densed report of said trial I here annex, marked C. I 
was present at said trial, and know that the results 
stated in said condensed report are true; and I do not 
know of any better engine regulated by a throttle valve 
than the one brought in competition with the Corliss 
engine on said trial.

Extract from the Condensed Report of a trial between a Cor - 
liss Steam Engine , manufactured by William A. Harris , 
of Providence , R. 1 ., and an engine of the ordinary con¬ 
struction , built by Lowe , Pacific Iron 1 VorJcs, Rridgeport , 
Connecticut. 

“For the past four weeks a trial has been going on between the 
Lowe and Harris engines, at the Plate Works on State street. 
Mi* Lowe was present a portion of the time, and made a per¬ 
sonal trial of both engines. He began what may be termed an 
informal trial with his own engine, commencing on the mornin^ 

^ o ^3 



39 


of the 24th of August. At the expiration of Saturday, the 
29th, his engine had expended 39,990 lbs. of coal, and rolled 
1,248, 8 by 12 inch plates of 9-16 inch thickness, down to the 
thickness required for the manufacture of Britannia goods. The 
next week, commencing on Monday, the 31st, he made a trial 
of the Harris new engine. On the day ending September 5th, 
the new engine had rolled 1,375 plates, and burnt 25,810 lbs. 
of coal. The new engine it will be seen had, therefore, con¬ 
sumed 14,180 lbs. of coal less than the Lowe engine, and yet 
had turned out 127 plates more than it had, although during the 
running of the Harris engine, the rolls were not in use for seven 
hours. 

The informal trial was pretty conclusive, and clearly demon¬ 
strated the superiority of the Corliss engine. Before Mr. Har¬ 
ris commenced his trial, he had one boiler that supplied steam 
for other purposes than motive power detached, so that the 
steam generated by said boiler was not used in connection with 
the engines. The fuel under the three remaining boilers was 
carefully weighed and accounted for. With Mr. Lowe’s infor¬ 
mal trial the boiler was not detached, which accounts for the 
excess in figures in the two previous weeks. 

On the 7th, Mr. Harris began his trial of the two engines. 
He commenced with his own engine, and at the end of the week 
had consumed 18,875 lbs. of coal, and had rolled 1,532 plates. 
During four days of the next week Lowe’s engine had consumed 
21,635 lbs. of coal, and had rolled 700 plates. The average 
consumption of coal per da} 7 upon the Harris engine is 3,146 
lbs. ; the average on the Lowe machine being 5,409, a saving 
by the former pf 2,263 lbs., or 41 and 8-10 percent. Mr. 
Harris ran his engine three days with two boilers only, instead 
of three. An attempt was made to run Lowe’s engine with two 
boilers, but after working an hour and three-quarters, the engi¬ 
neer was compelled to attach the third boiler. The speed of 
the new engine is fifty-five revolutions per minute, and, at one 
time, Friday, the 11th instant, an indicator diagram was taken, 
showing an increase of the load in four revolutions of 50 37- 
100 horse-power without affecting the speed. On this day 
there were 330 plates turned out, being the largest number ever 
rolled at these works. Attached to both engines is a " counter.” 
This machine faithfully records every revolution.”

familiar with the business of that company and have been since 
the above named date ; that the Royalties have been credited to 
the account of George II. Corliss, for his improvements in 
steam engines, upon every engine sold by the company con¬ 
taining these improvements, and that such Royalties from the 
10th day of March, 1863, to the present time, amount to one

dollars and 41 cents, ($114,485 41.) ; that the Royalties of the 
past year amounted to seven thousand and ninety-nine dollars 
and eighty-eight cents, ($7,099 88,) which is included in the 
above ; that the aggregate amount of business done by the com¬ 
pany since March 10, 1863, is more than three times as much 
as the amount charged for the steam engines on which Royalties 
have been credited ; that the said Corliss has a Patent for an im¬ 
proved boiler, which is built exclusively by the Corliss Steam 
Engine Company, and that the Royalties have been credited to 
his account since 1863, upon each of the boilers built under that 
patent, and that such Royalties since March 10th, 1863, amount 
to sixteen thousand nine hundred and nineteen dollars and fifty 
cents, ($16,919 50,) of which sum three thousand nine hun¬ 
dred and forty dollars and sixty-three cents, ($3,940 63,) was 
credited to him during the past year ; and that the said Corliss 
holds other Letters Patent for improvements which are used by 
the company in their manufactures, for the use of which no 
Royalties have been credited to him.

In the matter of the Petition of George II. Corliss , for an 
Extension oj his Letters Patent for improvements in Steam 
Engines. 

I, William Corliss, of North Providence, in the County of 
Providence, and State of Rhode Island, on oath depose and say, 
that I am the Treasurer of the Corliss Steam Engine Company, 
and have been acting in that capacity since January 1st, 1864. 
That I have read the affidavit of Edmund W. Raynsford, in this 
case, and that the same is true. The rates at which the Royal¬ 
ties have been credited to George H. Corliss, for the use of his 
patented improvements, were fixed by vote of the stockholders, 
March 20th, 1863, when he owned less than one-half of the 
stock of the Corporation. These rates being a large advance 
upon those formally allowed on this account by the company, 
occasioned dissatisfaction on the part of one of our largest 
stockholders, and became one of the causes of his retirement 
from the Company. In the fall of 1863, being desirous of aid¬ 
ing the Government, by request of the Secretary of the Navy, 
we entered into a contract with that department to furnish the 
steam machinery for two war vessels, of three and four thousand 
tons burden, respectively. These contracts involved the con¬ 
struction of two pairs of very large engines, with boilers and 
other appurtenances, aggregating in weight not less than fifteen 
hundred tons. To execute which as speedily as possible, we 
were compelled to make large additions to our works, involving 
an outlay of some two hundred and fifty thousand dollars—and 
to divert to a great extent the facilities and resources of the 
Company for a period of several years, from that part of our 
business in which the inventions of Mr. Corliss were used.

U. S. Patent Office, ) 
March 9th, 1863. $ 

In the matter of the application of George H. Corliss, for 
the extension of six patents reissued to him on the 12th of July, 
1859, for improvement in Steam Engines. 

The original patent was granted on the 10th of March, 1849, 
reissued on the 10th of May, 1851, and reissued, divided into 
six patents, on the 12th of July, 1859. The novelty of the 
invention has thus been three times affirmed by the offic(^; and 
four of the six patents have passed the ordeal of a most thorough 
and able examination in the Circuit Court of the United States 
for the District of Connecticut, the other two having never been 
controverted. The court was composed of Judge Nelson of the 
Circuit, and Judge Shipman of the District; the counsel on both 



43 


sides were among the most distinguished attorneys of the 
country. Experts were examined, models and drawings were 
exhibited, and every means which the highest abilities and great 
legal sagacity and experience could suggest, were used to secure 
a correct decision. The court, after a thorough investigation, 
decided that the invention was "new and patentable.” 

Incident to the present application for an extension of these 
patents, the question of novelty has been again submitted to the 
decision of this office, and the Examiner-in-charge has, in an 
original report, made a statement of facts and deductions there¬ 
from, strictly accordant with these several prior decisions. 

All the inventions alleged by the present remonstrants to 
interfere with the claims of the petitioner were before the court 
in the contest already referred to, and were minutely described 
and compared with or contrasted to his invention As nothing 
has been found in the record which appears to justify any excep¬ 
tion to the decision so uniformly reiterated, it is not now neces¬ 
sary to recite descriptions of the several inventions, nor so analyze 
them for the purpose of showing the essential difference of points 
alleged to be substantially the same. It is deemed sufficient for 
me to say that, viewing the invention comprehended in the 
petitioner’s several reissued patents, by the light of the entire 
record, and with the most careful consideration of the objections 
and arguments of the remonstrants and their learned counsel, 
I can find no sufficient reason for refusing the prayer of the 
petitioner, because of any lack of patentable novelty in his 
invention, whether with respect to the precise combination de¬ 
scribed in the several claims, or to their equivalents. 

No question has been raised in relation to the usefulness and 
importance to the public of this invention ; nor, in view of the 
testimony elicited, and of the admissions made, can such ques¬ 
tion be reasonably entertained, except in its bearing upon the 
question of the adequacy of the remuneration already realized 
by the inventor, in relation to which it may be affirmed that, the 
invention being confessedly of vast public value and importance, 
and the ingenuity, time, persistence in labor, capital invested 
originally, and expense incurred in introducing it to the public, 
and in defending the right guaranteed by the patent laws, all 
being great, the remuneration already received, as shown in the 
statement of the petitioner, is regarded as falling far short of an 
equitable reward. 

It is therefore ordered, that the said letters patent, numbered 
respectively 763, 759, 760, 758, 861, 762, and reissued to

The American Academy of Arts and Sciences award the 
Rumford Medal to Mr. Corliss for the improvements in Steam 
Engines, covered by these Letters Patent. 

PRESENTATION OF THE RUMFORD MEDALS. 

By the letter dated July 12, 1796, addressed to John Adams, Count Rum¬ 
ford requested the American Academy of Arts and Sciences to accept the 
five thousand dollars in United States’ stock, the interest to be applied to pre¬ 
miums, to be given to the authors of the most important discoveries or useful 
improvements, which shall be made in any part of the continent of America, 
or in any of the American islands, on heat or light, the preference always 
being given to such discoveries as shall, in the opinion of the Academy, tend 
most to promote the good of mankind. To be given in two medals, one of 
gold and one of silver, together of the intrinsic value of three hundred dol¬ 
lars. At a meeting of the Academy held in this city last evening, these med¬ 
als were presented to Mr. George H. Corliss, of Providence, R. I., for his 
improvements in the steam engine. The presentation was made by Dr. Asa 
Gray, President of the Academy, with the following remarks : 

ADDRESS OF THE PRESIDENT. 

Gentlemen of the Academy : 

At the last anniversary meeting, after a careful investigation by your appro¬ 
priate committee, you awarded the Rumford medal to Mr. George II. Corliss, 
for improvements of the steam engine. The gold medal and a silver dupli¬ 
cate have been struck and are now before us. The inventor whose genius 
you have thus recognized has responded to our call, and is now present. If 
it be your pleasure these medals will now be consigned to his hands. 

Mr. Corliss , the trust which our countryman, Count Rumford, charged this 
Academy to administer, empowered it to award these medals “ to the author 
of any important discovery or useful improvement on light or on heat, which 
shall have been made and published by printing, or in any way made known 
to the public, in any part of the continent of America, or of any of the Ameri¬ 
can islands; preference being always given to such discoveries as shall, in the 
opinion of the Academy, tend most to promote the good of mankind.” 

As this is only the fifth occasion since the foundation of the trust upon 
which this premium has been given, it may well be inferred that the Academy 
has in no case bestowod it inconsiderately. 

It has required the discovery or invention to be real, original and important. 
It is not restricted to considerations of direct practical benefit, but it may, as it 





45 


did in the first instance, in the case of the oxyhydrogen blow pipe, honor a 
discovery of much scientific interest, the uses of which are limited. It 
would not hesitate to crown any successful, however recondite or theoretical 
investigation within the assigned domain, being confident that no considerable 
increase of our knowledge of the laws and forces of Nature is likely to 
remain unfruitful. But the Academy rejoices when, as now, it can signalize 
an invention which unequivocally tends to promote that which the founder 
had most at heart, and commended to our particular regard, the material good 
of mankind. 

Without entering into details, it will be possible to state the ground upon 
which the present award has been made. It is for the abolition of the throttle 
valve of the steam engine, and the transference of the regulation by the gov¬ 
ernor to a system of induction-valves of your own invention ; with the advan¬ 
tage of a large saving in fuel, and, what is often more important in manufac¬ 
turing industry, the maintenance of perfectly uniform motion under varying 
work. 

■Previous to your improvements the regulation of the power and velocity of 
the steam engine was universally effected by an instrument placed in the 
steam pipe, well named the throttle valve, being used to choke off the steam 
in its passage from the boiler, to reduce more or less its pressure before it 
was allowed to act within the engine. Avoiding this wasteful process, your 
engine embodies within itself a principle by which it appropriates the full, 
direct and expansive force of the steam, and measures out for itself at each 
stroke, with the utmost precision, the exact quantity necessary to maintain 
the power required. 

In the most approved engines previously used for manufacturing purposes, 
the valves employed were comparatively difficult to operate, too far from the 
piston, and in other respects unfit for working in connection with the governor. 
Their abandonment and the substitution of others suitable for the purpose 
that you had in view, demanded an entire change in the structure of the 
engine. 

In the reconstruction, your mastery of the resources of mechanism is con¬ 
spicuously shown. You introduced four valves to the cylinder, two for the 
induction and two for the eduction of the steam; and by your device of a 
wrist-plate, you give to each valve a rapid motion in opening and closing, 
and a slow motion after the closing has been effected, thus securing a perfec¬ 
tion in valve movements never before attained. The special object of these 
changes, and the gist of your invention, was to place the induction valves 
under the control of the governor, by which they are operated in opening 
through a mechanism from which they are released earlier or later in the 
stroke of the piston, according as more or less power is demanded of the 
engine,—the governor, with extreme sensibility, determining the point where 
the supply of steam should be cut off. Thus, at every stroke of the piston* 
just so much steam is accurately meted out to the cylinder as is needed to 
maintain uniform velocity, and left to expand then, and by its expansion 
develop the maximum of propelling force. 

Allow me to read to the Academy a brief account of the Corliss engine, by 


46 


one of the most eminent of British engineers, Mr. J. Scott Russell, which 
must needs be free from personal or national prepossession. It is from one 
of the official reports on the Paris Universal Exhibition of 1867 : 

“ A third remarkable engine is American, both in invention and execution, 
and forms perhaps the most remarkable feature of the American department. 
It exhibits thoughtful design, ingenious contrivance, refined skill and admira¬ 
ble execution. It is singularty unlike an English engine. It has four ports 
on four different parts of the cylinder, two on one side and two on the oppo¬ 
site, each worked by a separate mechanism. These ports are worked by 
valves, not sliding, like our own, on flat surfaces, but sliding valves on cylin¬ 
drical surfaces. Close up to the cylinder, these valves cut off the steam with 
scarce a particle of waste room, and so economize to the utmost the high 
pressure steam which they admit, and which they use as expansively and as 
sparingly as possible. The mechanism by which these valves are moved, is 
to our eye outlandish and extraordinary; but it is, in truth, refined, elegant, 
most effectual and judicious; it spares steam to the utmost, but develops 
what it uses to most effect. Then it proportions in an admirable way the 
doses of steam it serves out to the continually varying quantity of work the 
engine has to do. The mechanism of its mechanical governor is wonderfully 
delicate and direct; the governor is sensitive to the most delicate changes of 
speed, and feels the slightest demand upon the engine for more or less work 
and steady speed. A mechanism as beautiful as the human hand releases or 
retains its grasp of the feeding-valve, and gives a greater or less dose of 
steam in nice proportion to each varying want. The American engine of 
Corliss everywhere tells of wise forethought, judicious proportion, sound 
execution, and exquisite contrivance.” 

It appears that within the twenty years since this machinery was perfected, 
more than 1,000 engines of the kind have been built in the United States, and 
several hundreds in other countries, giving an aggregate of not less than 250,- 
000 horse-power; that as to economy of fuel, evidence has been afforded to 
the Rumford committee, showing a saving over older forms of engine of 
about one-third. As to its other crowning excellence, uniformity of velocity, 
the purchasers of one of the engines, now in its eighteenth year of service, 
certify that, with the power varying from 60 to 360 horse-power within a min¬ 
ute, the speed of the engine is not perceptibly affected. 

It is worth noting that when these medals were voted to you, Mr. Corliss, 
just a century had passed since James Watt first patented his improvements 
of the steam engine. The vast results of these improvements—the difference 
between the engine when Watt found it and when he left it—make one of the 
most important chapters in the history of applied science. It is a great thing 
to say, but I may not withhold the statement that, in the opinion of those who 
have officially investigated the matter, no one invention since Watt’s time has 
so enhanced the efficiency of the steam engine, as this for which the Rumford 
medal is now presented to you. 

If Watt, or his partner, Bolton, could boast that they held the supply of 
that which almost everybody longed to have, power , you may justly felicitate 
yourself, and permit us to felicitate you upon your ability to supply a greater 


47 


1 


amount of steam power for tlie expenditure, and an exacter nicety in its gov¬ 
ernance, than any of your predecessors. 

In acknowledgement of this benefit, the American Academy, administering 
Count Iiumford s trust, now, by the hands of its presiding officer, presents to 
you these honorable testimonials of its high appreciation of what you have 
done. And the Fellows here assembled join with me, I am sure, in most sin¬ 
cere and hearty wishes that you may long enjoy this and similar distinctions 
along with more material rewards of your genius and skill,—hoping also that 
these may still be fruitful in yet other inventions, redounding to your honor 
and advantage and to the promotion of the good of mankind. 


Extract from Reports of the U. S. Commissioners of the 
Paris Universal Exposition of 1867. Printed at the Govern¬ 
ment printing office in Washington, D. C., 1869, “ pages 54, 
55 and 59.” 

corliss’s engine. 

The Corliss Steam-engine Company, of Providence, Rhode 
Island, have sent a 30 horse-power horizontal engine, finished 
with all the mechanical refinement tor which their works are 
justly celebrated. This engine has a large fly wheel which serves 
as a pulley for the broad driving belt; the frame is light and 
directly connects the main pillow-block with the head of the cyl¬ 
inder. No massive bed-plate is required for its support, but 
merely a solid foundation, on which may rest the cast-iron legs 
bolted to the pillow-block and the cylinder. There are four 
valves, two steam and two exhaust, placed at the extreme ends 
and directly upon the bore of the cylinder ; being made independ¬ 
ently adjustable, it follows that the time of commencement, 
extent, and rapidity of the movement of each may be arranged 
accurately to correspond with the theoretical requirements. 
Motion is imparted to them by a single eccentric acting through 
the medium of a vibrating disk, sometimes called a “ wrist- 
plate,” from which radiate the valve connections. Apart from 
the simplicity of the device, an important advantage is gained in 
the utilization of the crank motion’s known irregularity, to give 
the valves a rapid motion at the instant of opening or closing. 
The closing movement of the liberated steam-valves is effected 
by straight steel springs, coiled upon an arm of gentle curvature, 
whereby undue tension is avoided and a fulcrum always furnish¬ 
ed for the action of the springs. Air " dash-pots” arrest the 
motion of these springs when released. In the mechanism per- 



48 


taining the steam-valves is embodied a provision whereby in the 
course of its ordinary reciprocative movement (and at any point 
of the same) the parts directly and permanently connected with 
the valve may be detached from the control of the ‘ ‘ wrist-plate” 
and surrendered to the action of the steel spring. This detach¬ 
ment is effected by the impinging of a certain movable arm, or 
“ latch,” (forming part of the opening mechanism of the valve) 
against a “ stop” connected with and held in position by the 
governor. By this contact a slight deflection of the moveable 
arm is caused, resulting in such a disengagement of the appara¬ 
tus, that while the parts impelled by the “ wrist-plate” continue 
their movement unimpeded, the valve, on the contrary, becomes 
subject to the tension of the bent spring, which instantly draws 
it over the port. The detachment and consequent closing of the 
steam-valves is thus made dependent upon the position of the 
governor, while the latter, having no labor to perform, remains 
sensitive to the changes in speed. This engine, on account of 
its perfectly noiseless automatic motion; the extreme sensitive¬ 
ness of its cut off; its graceful and carefully studied proportions, 
as well as its highly polished surfaces, has attracted marked and 
appreciative attention. In a comparison of the different classes 
exhibited, it is significant to observe how minutely its features 
have been copied by noted builders of other nations, as indica¬ 
tive of the esteem with which they regard its novelties. 

The three most notable copies of the Corliss engine principle 
are by Messrs. Hick, Hargraves & Co., of Bolton, England, 
Messrs. Gebriider Sulzer, of Winterthur, Switzerland, and Mr. 
A. Duvergier, Lyons, France.
